Snowpack Summary

In the alpine, up to 15 cm of recent snow is heavily wind affected and sits above a variety of old snow surfaces including wind-scoured snow and faceted snow. At treeline and below, the recent snow sits on a widespread crust and pockets of surface hoar.

The snowpack is shallow and faceted with multiple crusts. Pockets of deeper snow may be found near ridges, gully features, and established avalanche paths. Average snowpack depths at treeline are between 50 and 90 cm.
